Printing quality problems
If the inside of the machine is dirty or paper has been loaded improperly,
there might be a reduction in print quality. See the table below to clear the
problem.
Pages print, but
they are blank.
The toner cartridge
is defective or out of
toner.
Redistribute the toner, if
necessary.
If necessary, replace the
toner cartridge.
The file may have
blank pages.
Check the file to ensure that
it does not contain blank
pages.
Some parts, such
as the controller or
the board, may be
defective.
Contact a service
representative.
The machine
does not print
PDF file correctly.
Some parts of
graphics, text, or
illustrations are
missing.
Incompatibility
between the PDF
file and the Acrobat
products.
Printing the PDF file as an
image may enable the file to
print. Turn on Print As
Image from the Acrobat
printing options.
It will take longer to
print when you print a
PDF file as an image.
The print quality
of photos is not
good. Images are
not clear.
The resolution of
the photo is very
low.
Reduce the photo size. If
you increase the photo size
in the software application,
the resolution will be
reduced.
Before printing,
the machine
emits vapor near
the output tray.
Using damp paper
can cause vapor
during printing.
This is not a problem. Just
keep printing.
The machine
does not print
special- sized
paper, such as
billing paper.
Paper size and
paper size setting
do not match.
Set the correct paper size in
the Custom Paper Size
Settings in the Paper tab in
the Printing Preferences
(See "Opening printing
preferences" on page 53).

Light or faded print • If a vertical white streak or faded area
appears on the page, the toner supply is low.
You may be able to temporarily extend the
toner cartridge life (See "Redistributing toner"
on page 91). If this does not improve the print
quality, install a new toner cartridge.
• The
paper may not meet paper specifications;
for example, the paper may be too moist or
rough (See "Print media specifications" on
page 111).
• If th
e entire page is light, the print resolution
setting is too low or the toner save mode is
on. Adjust the print resolution and turn the
toner save mode off. See the help screen of
the printer driver.
• A co
mbination of faded or smeared defects
may indicate that the toner cartridge needs
cleaning (See "Cleaning the inside" on
page 88).
• The
surface of the LSU part inside the
machine may be dirty (See "Cleaning the
inside" on page 88).

Dropouts If faded areas, generally rounded, occur
randomly on the page:
• A single sheet of paper may be defective.
Try reprinting the job.
• Th
e moisture content of the paper is uneven
or the paper has moist spots on its surface.
Try a different brand of paper (See "Print
media specifications" on page 111).
• Th
e paper lot is bad. The manufacturing
processes can cause some areas to reject
toner. Try a different kind or brand of paper.
• C
hange the printer option and try again. Go
to Printing Preferences, click Paper tab,
and set type to Thick (See "Opening printing
preferences" on page 53).
